It had to be black magic. Tim Southee and Trent Boult were swinging a
70-over old ball on the fourth morning. Both ways. Their skill accounted
for 13 of the 20 Sri Lankan wickets and confirmed Brendon McCullum's
Boxing Day assault as match winning. Christchurch witnessed New
Zealand's fifth victory in 2014, marking it their best year in Test history.

A target of 105 appeared straightforward, but Sri Lanka created a few
nervous moments for New Zealand along the way. A fluent Tom Latham was
undone by a ripping turner from debutant offspinner Tharindu Kaushal and
Hamish Rutherford was surprised by Shaminda Eranga's extra bounce and
lobbed a catch to gully.

Sri Lanka strived hard for further inroads. Ross Taylor and Kane
Williamson, though, were resolute and secured the Test in the seventh
over after tea on the fourth day.
The visitors had begun the day 10 runs behind and with five wickets in
hand, and their best chance was if their captain Angelo Mathews could
shepherd the tail. But even he was unprepared for the bouncer from
Southee, feathering an edge to the keeper off a front-foot pull early in
the morning.
Kaushal, the night-watchman, managed a couple of pleasing strokes
through square leg and cover off the front foot before a short ball in
the off-stump corridor did him. He was caught in two minds and before he
could pull the bat away, the edge flew to Mark Craig at second slip to
give Southee his first strike of the morning.

Dhammika Prasad was reluctant to get in line for most of his 17 balls
and was not ready when Southee sprung the trap with the fuller length -
twice. Ross Taylor grassed an absolute dolly, but before his face could
grow red another came his way and he caught it.
Sri Lanka did well to bat until lunch and their final-wicket pair even
forced the umpires to take a half hour's extension. The lead was 17 when
Mathews was dismissed, but Eranga and Suranga Lakmal conjured 59 runs
off 57 balls. Their clear-the-front-leg-and-swing tactic frustrated New
Zealand as they either watched the ball skirt past the outside edge or
skim to the cow-corner boundary. Boult broke through and earned himself
and his fellow bowlers some well-deserved rest after 196 testing overs
across the two innings.
